[Tutor] bar code

[Martin Stevens]

If i remember correctly there is some form of check sum in barcodes
to make sure they are correct and there are various different formats

i.e. 8 digit and 15 digits (iirc)

In the 15 digits one the country code is the first 5(i think) numbers
that the product was produced in.
